text: "We consider the quantum ferromagnetic Heisenberg model in three dimensions,
for all spins S ≥ 1/2. We rigorously prove the validity of the spin-wave approximation
for the excitation spectrum, at the level of the first non-trivial contribution
to the free energy at low temperatures. Our proof comes with explicit, constructive
upper and lower bounds on the error term. It uses in an essential way the bosonic
formulation of the model in terms of the Holstein-Primakoff representation. In
this language, the model describes interacting bosons with a hard-core on-site
repulsion and a nearest-neighbor attraction. This attractive interaction makes
the lower bound on the free energy particularly tricky: the key idea there is
to prove a differential inequality for the two-particle density, which is thereby
shown to be smaller than the probability density of a suitably weighted two-particle
random process on the lattice.\r\n"

text: We present a new, simpler proof of the unconditional uniqueness of solutions
to the cubic Gross-Pitaevskii hierarchy in ℝ3. One of the main tools in our analysis
is the quantum de Finetti theorem. Our uniqueness result is equivalent to the
one established in the celebrated works of Erdos, Schlein, and Yau.

text: Multiple plant developmental processes, such as lateral root development,
depend on auxin distribution patterns that are in part generated by the PIN-formed
family of auxin-efflux transporters. Here we propose that AUXIN RESPONSE FACTOR7
(ARF7) and the ARF7-regulated FOUR LIPS/MYB124 (FLP) transcription factors jointly
form a coherent feed-forward motif that mediates the auxin-responsive PIN3 transcription
in planta to steer the early steps of lateral root formation. This regulatory
mechanism might endow the PIN3 circuitry with a temporal 'memory' of auxin stimuli,
potentially maintaining and enhancing the robustness of the auxin flux directionality
during lateral root development. The cooperative action between canonical auxin
signalling and other transcription factors might constitute a general mechanism
by which transcriptional auxin-sensitivity can be regulated at a tissue-specific
level.

text: The immune response relies on the migration of leukocytes and on their ability
to stop in precise anatomical locations to fulfil their task. How leukocyte migration
and function are coordinated is unknown. Here we show that in immature dendritic
cells, which patrol their environment by engulfing extracellular material, cell
migration and antigen capture are antagonistic. This antagonism results from transient
enrichment of myosin IIA at the cell front, which disrupts the back-to-front gradient
of the motor protein, slowing down locomotion but promoting antigen capture. We
further highlight that myosin IIA enrichment at the cell front requires the MHC
class II-associated invariant chain (Ii). Thus, by controlling myosin IIA localization,
Ii imposes on dendritic cells an intermittent antigen capture behaviour that might
facilitate environment patrolling. We propose that the requirement for myosin
II in both cell migration and specific cell functions may provide a general mechanism
for their coordination in time and space.

text: 'Gene expression is controlled primarily by interactions between transcription
factor proteins (TFs) and the regulatory DNA sequence, a process that can be captured
well by thermodynamic models of regulation. These models, however, neglect regulatory
crosstalk: the possibility that noncognate TFs could initiate transcription, with
potentially disastrous effects for the cell. Here, we estimate the importance
of crosstalk, suggest that its avoidance strongly constrains equilibrium models
of TF binding, and propose an alternative nonequilibrium scheme that implements
kinetic proofreading to suppress erroneous initiation. This proposal is consistent
with the observed covalent modifications of the transcriptional apparatus and
predicts increased noise in gene expression as a trade-off for improved specificity.
Using information theory, we quantify this trade-off to find when optimal proofreading
architectures are favored over their equilibrium counterparts. Such architectures
exhibit significant super-Poisson noise at low expression in steady state.'

text: Contrary to the pattern seen in mammalian sex chromosomes, where most Y-linked
genes have X-linked homologs, the Drosophila X and Y chromosomes appear to be
unrelated. Most of the Y-linked genes have autosomal paralogs, so autosome-to-Y
transposition must be the main source of Drosophila Y-linked genes. Here we show
how these genes were acquired. We found a previously unidentified gene (flagrante
delicto Y, FDY) that originated from a recent duplication of the autosomal gene
vig2 to the Y chromosome of Drosophila melanogaster. Four contiguous genes were
duplicated along with vig2, but they became pseudogenes through the accumulation
of deletions and transposable element insertions, whereas FDY remained functional,
acquired testis-specific expression, and now accounts for ∼20% of the vig2-like
mRNA in testis. FDY is absent in the closest relatives of D. melanogaster, and
DNA sequence divergence indicates that the duplication to the Y chromosome occurred
∼2 million years ago. Thus, FDY provides a snapshot of the early stages of the
establishment of a Y-linked gene and demonstrates how the Drosophila Y has been
accumulating autosomal genes.

text: We show that the Galois group of any Schubert problem involving lines in projective
space contains the alternating group. This constitutes the largest family of enumerative
problems whose Galois groups have been largely determined. Using a criterion of
Vakil and a special position argument due to Schubert, our result follows from
a particular inequality among Kostka numbers of two-rowed tableaux. In most cases,
a combinatorial injection proves the inequality. For the remaining cases, we use
the Weyl integral formulas to obtain an integral formula for these Kostka numbers.
This rewrites the inequality as an integral, which we estimate to establish the
inequality.

text: Synapsins (Syns) are an evolutionarily conserved family of presynaptic proteins
crucial for the fine-tuning of synaptic function. A large amount of experimental
evidences has shown that Syns are involved in the development of epileptic phenotypes
and several mutations in Syn genes have been associated with epilepsy in humans
and animal models. Syn mutations induce alterations in circuitry and neurotransmitter
release, differentially affecting excitatory and inhibitory synapses, thus causing
an excitation/inhibition imbalance in network excitability toward hyperexcitability
that may be a determinant with regard to the development of epilepsy. Another
approach to investigate epileptogenic mechanisms is to understand how silencing
Syn affects the cellular behavior of single neurons and is associated with the
hyperexcitable phenotypes observed in epilepsy. Here, we examined the functional
effects of antisense-RNA inhibition of Syn expression on individually identified
and isolated serotonergic cells of the Helix land snail. We found that Helix synapsin
silencing increases cell excitability characterized by a slightly depolarized
resting membrane potential, decreases the rheobase, reduces the threshold for
action potential (AP) firing and increases the mean and instantaneous firing rates,
with respect to control cells. The observed increase of Ca2+ and BK currents in
Syn-silenced cells seems to be related to changes in the shape of the AP waveform.
These currents sustain the faster spiking in Syn-deficient cells by increasing
the after hyperpolarization and limiting the Na+ and Ca2+ channel inactivation
during repetitive firing. This in turn speeds up the depolarization phase by reaching
the AP threshold faster. Our results provide evidence that Syn silencing increases
intrinsic cell excitability associated with increased Ca2+ and Ca2+-dependent
BK currents in the absence of excitatory or inhibitory inputs.

text: We investigate weighted straight skeletons from a geometric, graph-theoretical,
and combinatorial point of view. We start with a thorough definition and shed
light on some ambiguity issues in the procedural definition. We investigate the
geometry, combinatorics, and topology of faces and the roof model, and we discuss
in which cases a weighted straight skeleton is connected. Finally, we show that
the weighted straight skeleton of even a simple polygon may be non-planar and
may contain cycles, and we discuss under which restrictions on the weights and/or
the input polygon the weighted straight skeleton still behaves similar to its
unweighted counterpart. In particular, we obtain a non-procedural description
and a linear-time construction algorithm for the straight skeleton of strictly
convex polygons with arbitrary weights.

text: We study the characteristics of straight skeletons of monotone polygonal chains
and use them to devise an algorithm for computing positively weighted straight
skeletons of monotone polygons. Our algorithm runs in O(nlogn) time and O(n) space,
where n denotes the number of vertices of the polygon.

text: We investigate weighted straight skeletons from a geometric, graph-theoretical,
and combinatorial point of view. We start with a thorough definition and shed
light on some ambiguity issues in the procedural definition. We investigate the
geometry, combinatorics, and topology of faces and the roof model, and we discuss
in which cases a weighted straight skeleton is connected. Finally, we show that
the weighted straight skeleton of even a simple polygon may be non-planar and
may contain cycles, and we discuss under which restrictions on the weights and/or
the input polygon the weighted straight skeleton still behaves similar to its
unweighted counterpart. In particular, we obtain a non-procedural description
and a linear-time construction algorithm for the straight skeleton of strictly
convex polygons with arbitrary weights.

text: In this paper, we consider the fluctuation of mutual information statistics
of a multiple input multiple output channel communication systems without assuming
that the entries of the channel matrix have zero pseudovariance. To this end,
we also establish a central limit theorem of the linear spectral statistics for
sample covariance matrices under general moment conditions by removing the restrictions
imposed on the second moment and fourth moment on the matrix entries in Bai and
Silverstein (2004).

text: Through metabolic engineering cyanobacteria can be employed in biotechnology.
Combining the capacity for oxygenic photosynthesis and carbon fixation with an
engineered metabolic pathway allows carbon-based product formation from CO2, light,
and water directly. Such cyanobacterial 'cell factories' are constructed to produce
biofuels, bioplastics, and commodity chemicals. Efforts of metabolic engineers
and synthetic biologists allow the modification of the intermediary metabolism
at various branching points, expanding the product range. The new biosynthesis
routes 'tap' the metabolism ever more efficiently, particularly through the engineering
of driving forces and utilization of cofactors generated during the light reactions
of photosynthesis, resulting in higher product titers. High rates of carbon rechanneling
ultimately allow an almost-complete allocation of fixed carbon to product above
biomass.

text: We investigate the quantum interference shifts between energetically close
states, where the state structure is observed by laser spectroscopy. We report
a compact and analytical expression that models the quantum interference induced
shift for any admixture of circular polarization of the incident laser and angle
of observation. An experimental scenario free of quantum interference can thus
be predicted with this formula. Although this study is exemplified here for muonic
deuterium, it can be applied to any other laser spectroscopy measurement of ns-n′p
frequencies of a nonrelativistic atomic system, via an ns→n′p→n′′s scheme.

text: 'We investigate the Taylor-Couette system where the radius ratio is close
to unity. Systematically increasing the Reynolds number, we observe a number of
previously known transitions, such as one from the classical Taylor vortex flow
(TVF) to wavy vortex flow (WVF) and the transition to fully developed turbulence.
Prior to the onset of turbulence, we observe intermittent bursting patterns of
localized turbulent patches, confirming the experimentally observed pattern of
very short wavelength bursts (VSWBs). A striking finding is that, for a Reynolds
number larger than that for the onset of VSWBs, a new type of intermittently bursting
behavior emerges: patterns of azimuthally closed rings of various orders. We call
them ring-bursting patterns, which surround the cylinder completely but remain
localized and separated in the axial direction through nonturbulent wavy structures.
We employ a number of quantitative measures including the cross-flow energy to
characterize the ring-bursting patterns and to distinguish them from the background
flow. These patterns are interesting because they do not occur in the wide-gap
Taylor-Couette flow systems. The narrow-gap regime is less studied but certainly
deserves further attention to gain deeper insights into complex flow dynamics
in fluids.'

text: We investigate the dynamics of ferrofluidic wavy vortex flows in the counter-rotating
Taylor-Couette system, with a focus on wavy flows with a mixture of the dominant
azimuthal modes. Without external magnetic field flows are stable and pro-grade
with respect to the rotation of the inner cylinder. More complex behaviors can
arise when an axial or a transverse magnetic field is applied. Depending on the
direction and strength of the field, multi-stable wavy states and bifurcations
can occur. We uncover the phenomenon of flow pattern reversal as the strength
of the magnetic field is increased through a critical value. In between the regimes
of pro-grade and retrograde flow rotations, standing waves with zero angular velocities
can emerge. A striking finding is that, under a transverse magnetic field, a second
reversal in the flow pattern direction can occur, where the flow pattern evolves
into pro-grade rotation again from a retrograde state. Flow reversal is relevant
to intriguing phenomena in nature such as geomagnetic reversal. Our results suggest
that, in ferrofluids, flow pattern reversal can be induced by varying a magnetic
field in a controlled manner, which can be realized in laboratory experiments
with potential applications in the development of modern fluid devices.

text: 'The straight skeleton of a polygon is the geometric graph obtained by tracing
the vertices during a mitered offsetting process. It is known that the straight
skeleton of a simple polygon is a tree, and one can naturally derive directions
on the edges of the tree from the propagation of the shrinking process. In this
paper, we ask the reverse question: Given a tree with directed edges, can it be
the straight skeleton of a polygon? And if so, can we find a suitable simple polygon?
We answer these questions for all directed trees where the order of edges around
each node is fixed.'

text: Auxin participates in a multitude of developmental processes, as well as responses
to environmental cues. Compared with other plant hormones, auxin exhibits a unique
property, as it undergoes directional, cell-to-cell transport facilitated by plasma
membrane-localized transport proteins. Among them, a prominent role has been ascribed
to the PIN family of auxin efflux facilitators. PIN proteins direct polar auxin
transport on account of their asymmetric subcellular localizations. In this review,
we provide an overview of the multiple developmental roles of PIN proteins, including
the atypical endoplasmic reticulum-localized members of the family, and look at
the family from an evolutionary perspective. Next, we cover the cell biological
and molecular aspects of PIN function, in particular the establishment of their
polar subcellular localization. Hormonal and environmental inputs into the regulation
of PIN action are summarized as well.
